BACKGROUND

Embodiments of the present disclosure relate to integrity assurance of files, and more particularly to system and method for integrity assurance in a virtual environment.

Files are a set of records kept together which have to be recorded and maintained. In certain situations, a chain of files have to be maintained. Further, in such a condition, the main purpose is to ensure that the chain of files are not invaded or tampered. Hence maintaining the integrity of the files and assuring a safety of the files is a preliminary criterion.

In one approach, one or more files are stored in a storage medium, which has to be transmitted to a target environment. In such systems an access control security system is implemented to restrict an access to the one or more files or any other related resources. Hence the system is protected from being invaded or tampered. However, in such systems, the one or more files must be transmitted in the form of packets. Hence the control access security system is not efficient to protect the packets of files from being contaminated from a third party.

In another approach, the system uses a processor and an authenticator, wherein the processor is used to convert a received data or received files into program files. Further, the authenticator is configured to selectively sign the program files using a key which is associated with one or more devices for which the program file is assigned or designed. However, in such systems, verification of the encrypted file is not being done. Hence, the system does not ensure if the received data or the received files are same as original data or original files.

Hence, there is a need for an improved system and method for integrity assurance in a virtual environment to address the aforementioned issues.

A system for integrity assurance in a virtual environment comprising: a memory configured to receive and store one or more artifacts; a processing subsystem operatively coupled to the memory, and configured to: create one or more binary files for one or more stored artifacts; send a request to the blockchain platform to trigger a crypto sealing process for the one or more artifacts; receive a command from the block chain platform to start a crypto sealing process for the one or more artifacts; seal the one or more artifacts using an encryption cryptographic key upon starting the crypto sealing process, wherein the encryption cryptographic key is generated by the blockchain platform and stored in the blockchain platform; store one or more crypto sealed artifacts, sealed based on the command from the blockchain platform, to a repository; request the blockchain platform to trigger a verification process of one or more copied artifacts for integrity assurance; receive a command from the blockchain platform to start the verification process for the one or more sealed artifacts; receive a decryption cryptographic key from the blockchain platform to verify the one or more crypto sealed artifacts, wherein the decryption cryptographic key is generated by the blockchain platform and stored in the blockchain platform; and verify the one or more crypto sealed artifacts based on the decryption cryptographic key received from the blockchain platform.
 2. The system as claimed in claim 1, wherein the one or more artifacts comprises one or more computer files or one or more by-products.
 3. The system as claimed in claim 1, further comprises a development unit operatively coupled to the memory, and configured to: develop the one or more artifacts; store one or more developed artifacts in a version control system; and transmit one or more stored artifacts to the memory.
 4. The system as claimed in claim 1, further the processing subsystem is configured to deploy one or more verified artifacts to a production unit.
 5. The system as claimed in claim 4, wherein the production unit comprises a development platform, a quality assurance platform, an operation platform or a production platform.
 6. A method for integrity assurance in a virtual environment comprising: receiving and storing, by a memory, one or more artifacts; creating, by a processing subsystem, one or more binary files for one or more stored artifacts; sending a request, by the processing subsystem, to the blockchain platform to trigger a crypto sealing process for the one or more artifacts; sending a command, by the blockchain platform, to the processing subsystem to trigger a crypto sealing process for the one or more artifacts based on the request by the processing subsystem; sealing, by the processing subsystem, the one or more artifacts using an encryption cryptographic key upon triggering the crypto sealing process, wherein the encryption cryptographic key is generated by the blockchain platform and stored in the blockchain platform; storing, by the processing subsystem, one or more crypto sealed artifacts, to a repository; requesting, by the processing subsystem, the blockchain platform to trigger a verification process of one or more copied artifacts for integrity assurance; sending a command, by the blockchain platform, to the processing subsystem to start the verification process for the one or more sealed artifacts; sending a decryption cryptographic key, by the blockchain platform, to the processing subsystem to verify the one or more crypto sealed artifacts, wherein the decryption cryptographic key is generated by the blockchain platform and stored in the blockchain platform; and verifying, by the processing subsystem, the one or more crypto sealed artifacts based on the decryption cryptographic key received from the blockchain platform.
 7. The method as claimed in claim 6, wherein receiving and storing one or more artifacts comprises: developing, by a development unit, the one or more artifacts; storing, by the development unit, one or more developed artifacts in a version control unit; and transmitting, by the development unit, one or more stored artifacts to the memory.
 8. The method as claimed in claim 6, further comprises deploying, by the processing subsystem, one or more verified artifacts to a production unit.
